` HAIE-CUELING nEvIcE .Application led October 4, 1923. Serial No.666,636.

\ To all whom it 'may cof/wem.'

' Be it known that I, JOSEF KRYsZ'rOFIAK, a citizen of the Republic ofPoland, and residing ,at 4174 Park Avenue, New York city, have inventedcertain new and useful :Improvements in Hair-Curling Devices, of whichthe following is a specification.

AMy invention relates to hair curling devices for producing permanent*waves in hair, and ,more particularly to the typev oidevices disclosedin my United States Letters Patent, No. 1,474,334, November '13, 1923,.on which this application animprovement. v

The object of this invention is? to provide Aa pencil for use in haircurling devices, so constructed as to enable the .operator to securelywrap the' strand of hair closely -around the pencil preparatory totreatment, '20 and to retain the hair in itsl proper position on thepencil and under the desired strain, during the operation of curling it.

I have found it to beef vital importance, in practice, to wrap the hairtightly upon the pencil and to hold it firmly-inplace,

-in order to secure, theproper wave, for .the 'reason that a permanentWave is accomplished by rearrangin the cells of the cortex and cuticleof the air,l and causing 3Q the cells to'remain in their new positions.

It is necessary, therefore, to provide means whereby the hair issecurely held inposi tion on the pencil during the operation of curling.j

Refei'ring tothe drawing Fig. 1 -is an assembled view of plete haircurling device.

F g. 2 1s a vlew ofthe pencil around which my comthe hair is wound andsecured.

' Fig. 3 is a view partly in section, of the pencil.

' Fig. 4 is a sectional view of Fig. 3. at 4.-4, looking from the left.

Fig. 5 'is an end view ofthe tubular ratchf et v18.

This invention applies more especially to the pencils used in haircurling devices. Fig. I shows one form of curling device, with thepencil located therein, in dotted 50 lines.

I wish to make it clear that my pencil isi not restricted in its use toany particular form of heater, las it is my intention to furnish thesepencils for use generally with u all forms of heaters in practice.

My pencil comprises a' sleeve, 11, on which the strand 'of lhair iswound, a head, 8, and a terminal, 12, rotated by the head. A ratchetdevice is located between the head, 8, on the one hand and the terminal,12, and the sleeve, 11, on the other, as hereinafter described Thesleeve, 11, is tubular in form, having a smaller diameter at theterminal end and a gradually increasing diameter towards the center ofthe sleeve. The balance of the length of the sleeve may be slightly.tapered. The thickness of the walls of the sleeve, 11, may be uniform orsubstantially so.v Rotatably assembled at one endfof the sleeve, 11; isa terminal, 12, provided with a shoulder, 21, `and a portion, 20, ofless diameter than the terminal, 12, and having a free t inthe smallerend of the sleeve,

11.- The end'oif: the terminal, 12, is slotted at 13, or otherwiseprovided with means for securing the scalp endtof the strand of hair tothe same. In the present instance, the slot, 13,-, provides means for"securing the hair lto the pencil by means of a string or tape. It Lwouldnot depart from the spirit of my invention to provide a clamp or -springat-the e nd of the sleeve for this purose.

Secured to, 'or integral with, the terminal, 12, is a-concentricallydisposed rod, 25, which runs through the longitudinal axis of the pencilto the opposite end of the same. The,

endof the rod, 25, is threaded to receive the nut, 9, which latter bearsagainst one end of a spiral spring, 32, the opposite endoi` whichv bearsagainst ashoulder, 33, in the hole, 26, passing through the head, 8. Theend of, the head, 8, opposite to the nut, 9, is provided with anenlarged diameter forming a sheulder, 15, against which the end `ot thetubular ratchet, 17, seats and alsoa second'fenlar diameter formingarecess, 16, to receive tv e'lar 'r end of the sleeve,11. The ratchet,17, is orced into or .otherwise secured to thehead 8, so that it rotateswith it.l The-end of the ratchet, 17, which seats I against theshoulder, 1 5, is partly enclosed,

iorming a keyhole opening asshown in Fig. 4,permittingthe rod end, 30,andthe liattened portion, 31, of the same to pass through the hole but'not permitting the -flattened por-. tion to rotate inthe hole.. Theshaft, 30, therefore, rotates with the head, 8. The outer end of theratchet. is provided with teeth, Q2, of about the shape shown in the ofthe ratchets 17, 18' and 19, normally en` gage'each'othe'r, as shown inFig. 3.

This construction permits the head, 8, and terminal,4 l2,`to jbe rotatedin either direction with referenceto the sleeve, 11, with a smoothratchet motion, and retain its adjusted position with as much force'asdesired. The resistance to the device rotating out of adjustment isdetermined by thev spring, 32, which can be adjusted by the nut,

9, to ve -a greater or less pressureup'on the tee th of the ratchets 1718 and 19. As the .ratchet-teeth pass over each other, the head,

l 8, moves longitudinally against the spring,

32, which latter at all times tends to bring and hold the ratchetmembers in the positions s'hown'in Fig. 5. Y ,v

The operation-ot my pencil will now be easilyunderstood. The strand ofhair to be curled is secured near the scalp end to the terminal, 12,.bysecuring'it with a string or otherwise, Aand is then'l wrapped upon thesleeve, 11.` The o posite end of the hair is e sleeve, 11, by` .tyin orotherwise. The terminal is now rotated by means of thehead, 8, withreference to the sleeve on which the hair is wound, until the strand ofhair `is tightly wound on the sleev'e.

'Thehair is usually subjected to a treatment Vof alkalis and oils, afterit is coiled upon the pencil, and is wrapped with felt or flannel or thelike,-one method being disclosed in my United States Patent No.1,440,163, is-

sued December 26, 1922. The pencil and hair and wrappings are insertedin the electric heater, 2, as shown in dotted lines in Fig. 1, and thehair lis heated for va given time to the degree desired. A fingeredspring clip, 7, holds the pencil in place in the heater. The current iscarried to the heater, 2, by leads, 9, secured to the handle, 4, by astrap, 5, insulated from the leads, 9, by insulating tube, 29, andclamped in position by bolt and nut, 27. Theheater, 2, is

provided with an insulating collar, '3, for handling it. A clamp, 28. isprovided at one end of the heater for the hair near the scalp, and isoperated by the heat insulatingv l collar, 6. similarly to the methoddisclosed.

iny my United States Letters Patent No. 1,474,334, November4 13, '1923.

the sleeve and the shaft, one ratchet member 1 adapted to be drivenbythe sleeve, another ratchet member adapted `to be driven by the shaft,both of said ratchet members having teeth facing in the same direction,a third ratchet member normally engaging therewith, and resilient vmeansadapted to hold all of the ratchet members in engagemen with each other.A

2. A pencil for a hair curling device, consisting of a sleeve upon whichthe hair may be Wound, a shaft in the sleeve, a ratchet member driven bythe sleeve, a ratchet member driven by the shaft, and ineans between andnormally engaged with both of the ratchet members, adapted to receive'motion in one direction only, alternately from one ratchet or theother. y

3. A pencil fora hair curling device,`com prising ya sleeve, a shaftvini-.the sleeve, a

ratchet rotated by the sleeve', another ratchet fecting a movement ,fthe sleeve.

5. A pencil for a hair curling device, comprising a sleeve, a ratchetadapted, to be rotated thereby in both directions, a head, a secondratchet adapted to be rotated thereby in both directions, a lockingdevice,'en gaged with both ratchets, free to move in onedirection only.-y

6. A pencil for a hair curling device, comprising a sleeve, arat-chetrotated thereby, a

shaft in the sleeye,a second ratchet adapted i to be rotated thereby,and meansvinterposed between the ratchets, adapted to be rotated in thesame directiomby either ratchet, to

prevent the movement' of the head fromv effecting'a movement of thesleeve.

,In testimony whereof, I aiiix my signature, in the presence of 'twowltnesses.
